Ex-Situ Tank Decommissioning and Environmental Validation ServicesRemoval of Underground Petroleum Storage Systems (UPSS) or fuel or chemical tanks is the preferred option per NSW EPA guidance, for dealing with disused or unwanted UPSS tanks as it allows for a more through and complete investigation and assessment of any potential contamination on the site. Tank removal and remediation of any residual contamination decreases environmental and OH&S risks at UPSS sites. This in turn, reduces the liability of the person responsible for the site and / or its owner while increasing potential land use options.

Benefits of the hard cell foams include economy, minimal excavation, resistance to hydrocarbons, solvents and other chemicals and its ability to be pumped over long distances as found in pipelines.
